SPOKE-SETTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 262,283, dated August8, 1882.

Application filed January 10, 1882. (No model.)

To all whom it may concern:

Be it known that I, ANDREW M. FIsHER, of Linden, county of Genesce,State of Michigan, have invented a new and useful Improvement in SpokeDriving and Setting Devices; and I declare the following to be a full,clear, and exact description of the same, such as will enable othersskilled in the art to which it pertains to make and use it, referencebeing bad to the accompanying drawing, which forms a part of thisspecification.

Myinvention consists of the combinations of devices and applianceshereinafter described, and more particularly pointed out in the claims.

In the drawing the figure is a view in elevation of an apparatusembodying my invention, and showing by dotted lines how the de vice maybe opened out so as to discharge the wheel.

Heretofore it has been customary to fasten the hub of the wheel betweentwo faces and bind the parts firmly together by a hand-screw,necessitating considerable time in the operation, or else some othertime-consuming means has been employed for the purpose.

It is the object of my invention to produce a means for accomplishingthe following objects: First, to effectually clam p the hub between twoface-plates which are located at opposite ends of the hub; second, tocenter it between the two face-plates; third, to effect the clamping bya single movement of a lever; fourth, to effectually engage the upper ordriving end of any spoke by a means which may be instantly disengagedfor the reception of a new spoke; fifth, to afford means for giving tothe spoke any predetermined set which shall give to the wheel thedesired dish.

To this end, A is a suitable frame.

B is an upright, provided with a face-plate, B, and this latter isprovided with a stud, b, for centering the corresponding end of a hub.

G is the other face-plate. It is hinged at 0, and may by suitableslot-aud-bolt fastenings, c 0 be adjusted nearer to or farther from theupright B, to correspond with any particular length of hub.

D is a cam with a handle or lever, D. It is pivoted at d, and impingesagainst the back of the hinged face-plate 0, so that when in use the camforces the face-plate firmly against the end of the hub, and a stud, 0,serves to center the wheel; but when opened out of engagement theface-plate C may be turned back and the wheel instantly released.

Eisastirrup adapted to bedropped down over a spoke, and slotted wedge Eserves to clamp the spoke firmly against the shoulder at e, whichdetermines the set of the spoke, and consequently the dish of the wheel.The heel of the stirrup E is preferably pivoted to an arm, E which ismade adjustable about its pivot c by a set-screw, 6 so that any desireddish may be given to a wheel.

By means of the adjustments of the spokesetting mechanism just describedand the adjustment of the face-plate C it is apparent that this onedeviceis adapted for all sizes of wheels,

and for any degree of dish.

I am aware that the forms ofcam mechanism may be varied somewhat; but Iwould have it understood that in this particular myinventioncontemplates any device which effects the clamping and releasing by acam-and-lever movement. So, also, other means may be devised foradjusting the plate 0 nearer to or farther from the hub, as also theadjustable arm E F represents a hub, and F one of its spokes in positionready to be driven.

By this device a wheel can be placed in this apparatus in a very fewseconds. Its spokes can be rapidlyand surely set and driven, and

the wheel be instantly discharged, ready for a new wheel.

I have found that I can very largely increase the work of any hand by anapparatus of this character beyond what he could accomplish by any ofthe ordinary devices now in use.

The slot in the wedge-block E permits it to descend to a firm bearingagainst the spoke, whether the latter be larger or smaller.

I also contemplate using at times a strap or rod extending down to thefloor from this block or the stirrup, so that the operator may, if hefinds it necessary, by placing his foot on the rod or strap, hold thestirrup or the block firmly down to its place while driving the spokeand prevent it from springing up off from the spoke.

rob

The whole stirrup mechanism may be adjusted up or down, it it is desiredto locate at a distance nearer to or farther from the hub. This may beeffected by means of a slot, I, and bolts 1.

Vhat I claim is 1. A spoke driving and setting device consisting of astationary face-plate provided with a centerin -stnd, a hingedface-plate provided with a centering-stud, and a cam and lever adaptedto impinge against the back of the said faceplate, whereby the plate maybe clamped upon the hub or released, substantially as described.

2. A stationary face-plate and a hinged faceplate governed by a cam andlever, each plate having a centering-pin, and the said hinged face-platemade adjustable to and from the stationary face-plate, substantially asdescribed.
